## Abstract The 3‐dimensional structure of the pheromone E__r__‐1 isolated from the ciliated protozoan __Euplotes raikovi__ has been determined in aqueous solution by ^1^H NMR spectroscopy. The structure of this 40‐residue protein was calculated with the distance geometry program DIANA on the basis
## Abstract The disulfide pairings of the two __Euplotes raikovi__ pheromones E__r__‐1 and E__r__‐2 have been determined by chemical and mass spectrometric analyses. Cystine‐linked peptides from thermolytic digestions of the native molecules were purified by reverse‐phase high performance liquid ch
## Abstract The NMR structures of the homologous pheromones E__r__‐1, E__r__‐10, and E__r__‐2 from the ciliated protozoan __Euplotes raikovi__ are compared. For all 3 proteins the molecular architecture is made up of an antiparallel 3‐helix bundle. The preservation of the core part of the structure
